In the electronic industrials, power control of AC motors is commonly used. For example power control of a washing machine motor, a vacuum cleaner motor or a coffee machine motor. The company Rejlers Ingenjörer AB has many projects where power control of AC motors is included. A prototype card for this task can save time and money for the company in the future and this is the reason for this thesis.The motors are power controlled by a TRIAC and control of the trigging pulses to the TRIAC. This card is modularly built and can easily be adapted for future projects where the power control of AC motors are included.The prototype card can be used as a subsystem in a larger electronics projects or as it is in lab environment for testing and evaluating new motors..

To be allowed to sell Z-suspended vehicles with dipped beam Xenon or LED lighting, Scania have to develop automatic headlight level control. This master?s thesis aims to be the foundation to that development.The thesis consists of several parts; a market analysis of how competitors to Scania and the general vehicle industry solve this problem; several available principles for detecting the amount of control needed; the construction of a test station for sensors, a control unit and components connected controlled by the control unit; a further theoretical and practical development of one principle ? one rotational sensor connected between the chassis and the back drive axis; a state flow model programmed in Simulink that produces the control signal for the headlight leveling from the sensor input.Lastly the thesis gives some recommendations to the further development and implementation of automatic headlight level control on Scania vehicles..

Föreliggande studies syfte var att undersöka validitet och intern konsistens för den svenska översättningen av Impaired control scale (ICS), en självskattningsskala som mäter grad av kontroll av alkoholkonsumtion. ICS består av subskalorna; Attempt control (AC), Failed control (FC) samt Predicted control (PC). Svar på ICS sammanställdes från respondenter (n = 203) som behandlats för alkoholproblem vid mottagningar i Västra Götaland. Faktoranalysen visade en bakomliggande faktor för AC, och två faktorer för FC respektive PC. Den interna konsistensen var god.

The purpose of this thesis is to analyze the design and function of an engine production management?s control system and its intended function, and to contrast it with the present management control systems in use on an operational level. Interviews conducted with employees from all levels of the engine production are the main source of this study?s empirical foundation. Information has also been gathered from relevant written material such as annual reports, internal documents etc.

This thesis has been carried out in collaboration with LEDtec International AB. LEDtec focuses on innovative solutions in LED screens. Everything from large advertising signs to welcome signs in cities, to screens indicating speeds or warning of heavy traffic. The task was to was to help them develop a new version of the control board that is used in some of their products. The reason for this is that their old control board is obsolete and the components that are on it, is no longer manufactured or in need to be renewed.

The purpose of this essay was to examine whether small businesses can avoid ac-counting crimes with a well-conducted internal control system. The questions we asked ourselves was, whether and if so, companies can prevent this from happening by using a internal control.In this essay we used a qualitative approach. Essential information was given to us from four different interviewees. We also worked from an inductive approach which means that we interviewed people without any earlier research to build on. The method also had a hermeneutical approach, which means that we made different interpretations based on the reference framework and the empirics.After the study had been carried out, we concluded that all evidence from this essay suggested that even small businesses need an internal control to protect their business.

En majoritet bland ledare i olika organisationer har en bakgrund som storasyskon eller ensambarn (Hudson, 1990). Denna studie genomfördes för att få svar på om personer med ledaransvar skiljer sig åt gällande syskonplats och locus of control jämfört med de personer som inte har ledaransvar. Ledare och medarbetare på en statlig myndighet svarade på en enkät gällande plats i syskonskara, erfarenhet av ledarskap och locus of control. Resultatet visade att sistfödda i detta urval hade en högre grad av intern locus of control än förstfödda vilket kan tyda på en annan typ av sistfödd på denna myndighet. Urvalet var dock bristfälligt (N = 48) och slutsats kunde inte dras utan att riskera ett felaktigt resultat..

The thesis was performed at Forsmarks Kraftgrupp AB in the department ofmechanical engineering, FTCM. Forsmark nuclear power plant has had problems with cracks in some of the controlrods which are placed in the reactor at Forsmark 3. To investigate the cause of this,material samples were taken from five of the damaged control rods. This sampling ofthe rods resulted too short rods to be transported in the shipping container to theinterim storage facility for used nuclear fuel in Oskarshamn. Control rods are crucial components in a nuclear reactor, regulating the reactoreffect by blocking or unblocking fuel rods. Control rods which have been in thereactor are always handled under water in order to protect against the radiation theyemit. The task was to design a control rod adapter that extends the control rod sotransport can be performed from Forsmark. The goal of the work was a complete setof blueprints so the control rod adapter can be manufactured and mounted on theshort control rods and then be transported to the interim storage facility. The work began with mapping of how control rods normally being handled from thereactor to the interim storage facility.

This study aims to examine the effect the evaluation system used by the Stockholm County Council, has on how the healthcare providers themselves conduct the evaluation regarding their own operations. This is done through a qualitative case study of the evaluation systems of the Stockholm County Council and of four primary healthcare producers concerning one primary healthcare contract. The evaluation systems were analysed using Merchant and Ver der Stede's (2007) framework for different types of control. In order to give a more detailed picture this framework was complemented with different types of performance measurement. The evaluation that the Stockholm County Council conducts was found to have little influence on the providers own evaluation with the exception of the quality indicators that are rewarded with a monetary bonus..

Syftet med vårt arbete har varit att beskriva hur kommunerna kvalitetssäkrar den interna kontrollen. Utifrån syftet har vi formulerat problemformuleringen. Kvalitetssäkrar kommuner sin interna kontroll och i så fall hur och med vilka aktiviteter utförs det? Vi valde att göra vår uppsats med hjälp av fallstudiemetoden. Vi utförde intervjuerna i tre kommuner och där intervjuade vi tre ekonomiansvarig/personer som arbetar med den interna kontrollen samt tre sakkunniga revisorer.

Värnamo Elnät owns and operates a ripple control system which is used to control loadsespecially when the grid is heavily loaded and for control of street lighting. This report aims atclarifying technical and economic aspects of the ripple control system?s future. The system wasinstalled from 1975 and onwards and its use was greater in those days when the controllableloads where greater then today, the current controllable load level is about 3 MW. The reporthighlights three different aspects of the ripple control system?s future ? retain the currentsystem, reinvest in a newer system or discontinue the system.In the report the author also discusses relevant connections to Smart Grids and future meteringsystems and tariffs.
